Abstract
A floating substructure made of a steel structure with ballast tanks provides buoyancy and stability to support a wind turbine generator in deep waters. Mooring lines directly attach to the substructure to provide stability. These mooring lines can also be directly anchored to the bed of a body of water, such as a seabed, to control movements. Different types of anchors can be used depending on the soil characteristic of the bed of the body of water.
Claims18
An offshore substructure comprising:
- a central hull;
- a plurality of legs positioned around the central hull;
- a plurality of braces, each of the plurality of braces being directly connected to the central hull and to one of the plurality of legs;
- ballast positioned in at least one of the central hull and the plurality of legs;
- and
- a plurality of moors, each one of the plurality of legs and the central hull being attached to a respective one of the plurality of moors at a first end, and each one of the plurality of moors being attached to an anchor at a second end.
3 more elements
An offshore substructure comprising:
- a central hull;
- four legs positioned around the central hull;
- a plurality of braces, each of the plurality of braces being directly connected to one of the four legs and to the central hull;
- a first pair of moors including a first moor and a second moor, each of the first moor and the second moor connected to a respective leg of a first pair of the four legs, the first moor of the first pair crossing from a first side of the second moor of the first pair to a second side of the second moor of the first pair when viewed from above the central hull;
- and
- a second pair of moors including a first moor and a second moor, each of the first moor and the second moor connected to a respective leg of a second pair of the four legs, the first moor of the second pair crossing from a first side of the second moor of the second pair to a second side of the second moor of the second moor when viewed from above the central hull.
